/* ** ** Swift/XRT hardness ratio for 3C 273. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 58199.290643 0.000434 0.42717 0.07242 0.97333 0 1.88868 0.17657 1.60401 0.14994 0.80679 0.11410 0.68607 0.09703 58199.291603 0.000527 0.47549 0.08304 0.95604 0 1.41445 0.14191 1.20069 0.12046 0.67255 0.09615 0.57027 0.08150 58199.292561 0.000431 0.43757 0.07593 0.98658 0 1.81743 0.17884 1.53800 0.15132 0.79526 0.11367 0.67501 0.09647 58199.293406 0.000414 0.55609 0.09959 0.97203 0 1.51788 0.16379 1.29027 0.13922 0.84408 0.12065 0.71386 0.10202 58199.294332 0.000512 0.35891 0.05943 0.97740 0 1.90835 0.16437 1.61566 0.13917 0.68493 0.09687 0.57900 0.08188 58199.295452 0.000608 0.31623 0.05173 0.96667 0 1.82633 0.14777 1.55138 0.12550 0.57754 0.08211 0.49112 0.06982 58199.296490 0.000431 0.49588 0.08682 0.97315 0 1.62585 0.16784 1.39302 0.14380 0.80623 0.11402 0.69081 0.09769 58199.297315 0.000394 0.52696 0.09295 0.96324 0 1.72549 0.18005 1.46171 0.15251 0.90926 0.12932 0.76916 0.10939 58199.298088 0.000379 0.49152 0.08665 0.98473 0 1.84682 0.19060 1.56970 0.16200 0.90774 0.12974 0.76920 0.10993 58199.298921 0.000454 0.44291 0.07644 0.98726 0 1.69995 0.16445 1.44775 0.14005 0.75293 0.10761 0.64017 0.09149 58199.299803 0.000428 0.40826 0.06849 0.95946 0 2.04437 0.18443 1.73333 0.15637 0.83463 0.11805 0.70540 0.09976 58199.300614 0.000382 0.43937 0.07593 0.96970 0 2.06818 0.20094 1.76378 0.17135 0.90869 0.12987 0.77521 0.11079 58199.301878 0.000883 0.35741 0.04268 0.98033 0 2.17561 0.13465 1.83232 0.11339 0.77757 0.07942 0.65388 0.06678
